Inventor: YANAGISAWA YOSHIO
IPC: B60R1/06
Filed: 1982-07-12
Abstract: PURPOSE:To facilitate the safety check at the rear outside of a trailer when a trailer tractor truck turns to the left or right by mounting a side rearview mirror at the front corner of the trailer and varying the direction of the mirror interlocking with the left- or right-turn of the trailer tractor truck. CONSTITUTION:Since a tractor truck turns to the right when a trailer tractor truck turns to the right, a coupling coupler (A) rotates clockwise. Thus the coupler (A) presses switches (B) and (C) that are made to adhere to the trailer truck body. As a result, current is applied to (D) and the (D) is expanded and then a mirror arm (E) jumps out. In addition, by pressing the switch (C), a transmission wire (F) moves and a mirror (G) turns its front toward the rear outside of the trailer. As a result, drivers can check the safety of the rear outside of the trailer. When the trailer tractor truck returns to the straight-drive status, the coupler (A) rotates counterclockwise and both arm (E) and mirror (G) return to the original positions. This applies also to the left-turn.

Title: Submarine baranching device
Inventor: TOMOSUGI TAMIO
IPC: H04B3/44
Filed: 1991-04-23
Abstract: PURPOSE:To prevent a surge from being given to a submarine cable system by connecting a feeding path to a submarine ground with a feeding path switching means and providing a resistor to absorb the surge so as to absorb the surge at the time of switching the feeding path. CONSTITUTION:Contacts r1-r4 in the initial state are connected as shown in figure and contact r3b, r4a are opened. Moreover, a submarine branching device H is located close to a terminal station A. At first a voltage is gradually increased or decreased to increase a current to both terminal stations A, B. Since terminal stations A-C are all at the same potential when the current is on the brinking state of a sensing current of a relay RL1, a voltage close to the voltage of the terminal station A is being stored in the submarine cable around the submarine branching device H. When the current between the terminal stations A, B reaches the sensing current of the relay RL1, the contact r1 is switched to the position shown in broken lines. In this case, the charge stored in the submarine cable at the terminal station C is going to flow through a sea water ground G, but the surge is absorbed by the resistor R and no surge is exerted to a repeater around the submarine branching device.
